Thinking it may be time to sell and let someone else enjoy this uncommon design. Built per instructions using recommended gear. Was a quick tape job for covering when built which is starting to look really tired. Flown in 2010 season, but battery is a few years old. RTF right now if you don't feel like recovering it right away, but at least re-do the tape hinges. UV aging is evident and I doubt they would hold up to another season of flying without trouble.
